Test 2: Trauma Flashcards
When did Connecticut’s trauma system begin?
October of ‘95
What are the criteria for a level 1 trauma center?
>1200 traumas per year
>240 admissions with injury severity score (ISS) > 15
Avg. of > 35 pts with ISS of > 15 seen by trauma panel surgeon
What is ATLS? when was the first class and when did ACS take it on?
Advanced trauma life support. first class 1978. ACS took on ATLS =1980
What is included in standard precaution?
cap, gown, gloves, mask, shoe covers and goggles/face shield
What is a quick simple way to assess a patient in 10 seconds?
identify yourself, ask the patient his or her name and what happened.
When assessing a patient, an appropriate response confirms what?
ABCD - patient airway, sufficient air reserve for speech, sufficient perfusion to permit cerebration, clear sensorium
In primary survey what are the ABCDEE?
A = airway with c-spine protection, B = breathing with adequate oxygenation, C = circulation with hemorrhage control, D = disability, E = exposure/environment
What are some ways you can assess for circulation?
level of consciousness, skin color and temp, pulse and chacter
A patient only has a carotid pulse, ballpark their BP
60mmHg
A patient has a femoral pulse but not a radial, ballpark their BP
70mmHg
A patient has a radial pulse, ballpark their BP
at least 80mmHg
How can we assess for D - disability in the ABCDEs
baseline neurologic evaluation - GCS, pupillary response
Why do we do E - expose/environment during ABCDEs?
we completely undress he patient to prevent hypothermia and missed injuries
what is a high riding prostate?
urethra is torn, prostate feels higher than normal
is it okay to do a foley on someone with a high riding prostate?
no its contraindicated! their urethra is torn!
malgaigne fracture
(the penis points the the pathology)
what is DPL and what is it indicated for?
diagnostic peritoneal lavage. It is indicated in the evaluation of intraabdominal trauma specifically the small bowel(bleeding, perforation) (Note: Spiral CT of the abdomen has largely replaced DPL as an initial screening tool for intraabdominal trauma in the emergency setting.)
Pt wit fractured cribriform plate needs gastric tube, should you go NG or OG?
OG unless you want to stick it in their brain
What is included in the primary survey?
ECG, vitals, ABGs, SpO2 and CO2, urinary/gastric tubes, urinary output
what are the components of the secondary survey?
H&P including neuro, special diagnostic tests and reevaluation
when do you start secondary survey?
after primary survey! and ABCDEs are reassessed and vitals are RETURNING TO NORMAL
What is AMPLE?
allergies, medications, past illness, last meal, events/environment/mechanism
What volume hemothorax goes straight to the OR?
1500mL
In penetrating trauma should you just remove the object?
No! get proximal and distal control of the blood supply and then remove
During secondary survey of the head what do you want to do?
external exam, scalp palpation, eye and ear (watch for visual acuity, periorbital edema and occluded auditory canal)
what is zone 1 of the neck? and what do you have to worry about injury to this area?
sternal notch to cricoid – worry about the LUNGS, trachea, esophagus, spine, vertebral and PROXIMAL carotid arteries, and MAJOR THORACIC VESSELS. do CT angio, esophageal bronchogram
What muscle when penetrated would make you assume significant injury has occurred in the neck?
The platysma
What is zone 2 of the neck and what do you have to worry about in this area?
cricoid to angle of the mandible. worry about risks the carotid and vertebral arteries, jugular veins, esophagus, spine, LARYNX, and trachea. Zone 2 seems to be the easiest for surgical control
What is zone 3 of the neck and what do you have to worry about in this area?
angle of mandible and up. The DISTAL carotid and vertebral arteries, PHARYNX, and spine are all at risk.
What are some findings we look for in the neck (soft tissues)?
crepitus, hematoma, stridor, bruit
What do you need to do before Foley cath placement in injured patients?
DRE
Which of the following is the progression of shock?
a) Inadequate O2 –> Catecholamine surge –> Anearobic metabolism –> Cellular dysfunction –> Cell death
b) Catecholamine surge –> Inadequate O2 –> Anearobic metabolism –> Cellular dysfunction –> Cell death
c) Cell death –> Catecholamine surge –> Inadequate O2 –> Anaerobic metabolism –> Cellular dysfunction
d) Cellular dysfunction –> Cell death –> Catecholamine surge –> Inadequate O2 –> Anerobic metabolism
a) inadequate O2–>catecholamines–>anearobic metabolism–>cellular dysfunction–>cell death
What are signs of shock?
Altered LOC, anxiety, cold, diaphoretic, tachycardia, tachypnea (shallow), hypotensive, decrease urinary output
What are nonhemorrhagic shock examples?
tension pneumothorax, cardiac tamponade, cardiogenic, septic, neurogenic
What are hemorrhagic shock examples?
blood or fluid loss
how do you locate bleeding?
physical exam and diagnostic adjuncts (CXR, pelvic X-ray, FAST/DPL)
Which of the following is not included in the mnemonic “blood on the floor and four places more” when referring to looking for blood in 4 places.
a) Chest
b) Abdomen
c) Retroperitoneum
d) Spinal Column
e) Pelvis/Thigh
d) Spinal column
Bleeding interventions?
direct pressure/tourniquet, reduce pelvic volume, operation, splint fracture, angioembolization
What is 750mL (15%) or less BVL (blood volume loss) considered?
class I hemorrhage
What are signs of class I hemorrhage?
Slightly anxious, Normal BP, HR < 100, RR 14-20, UOP (urine output) 30 mL/h
